摘　　要：采用多因素正交试验方法进行PCBN可转位面铣刀铣削灰铸铁HT200的试验,通过最小二乘法和回归分析建立了铣削力经验公式模型。回归方程及回归系数的显著性检验表明所建立的模型可信度较高。试验结果表明3个方向的铣削力中,切向铣削力Fz最大,其次是轴向铣削力Fx和径向切削力Fy。通过对试验结果的分析,总结出了各铣削参数对于铣削力的影响变化规律,给出了切削参数的推荐取值范围。Multi-factor orthogonal experiment method is adopted to carry out experiment of milling gray cast iron HT200 using PCBN indexable face milling tool.Milling force empirical equation model is established by means of least-square method and regression analysis.Significance test of regression equation and regression coefficient showes the established model has high credibility.Test results show among three milling forces,the biggest one is tangential force Fz,the smallest one is radial force Fy,whereas value of axial force Fx is between Fz and Fy.Through analyzing experiment results,relationship of milling parameters influence on milling face is summarized.Recommendation of milling parameter value range is put forward.
